Problem in Target and profile

we created an hierarchy based on our project, we created a role and user based on it, we logged in to the user, now we are getting these error on target, we have not wrote any target code though, and we are also not getting the profile of people too, it is empty, Can someone help on this ?

So, i tried to give multiple role in context in target, this is why i was facing this error. The error has been solved.
